摘要： Described herein are batches of nanoscale phosphor particles having an average particle size of less than about 200 nm and an average internal quantum efficiency of at least 40%. The batches of nanoscale phosphor particles can be substantially free of impurities. Also described herein are methods of manufacturing the nanoscale phosphor particles by passing phosphor particles through a reactive field to thereby dissociate them into elements and then synthesizing nanoscale phosphor particles by nucleating the elements and quenching the resulting particles.
